In Windows 8, Refresh and Reset are the most useful while tools in repairing the Windows copy. But if you’re using Windows that you have installed yourself or that is not came pre-installed from OEM, then you may need the installation disc to use these tools. While using any of these tools, you may be stopped with the following message:

reagentc /setosimage /path C:Refresh /target C:Windows /index 1

  • Kapil Arya

    ^^ You would at least need the setup to proceed for this.

  • Please elaborate the same or explain step by step if possible.

  • Kapil Arya

    ^^ When you have setup with you, you can proceed as mentioned above. Inside the setup, look for install.wim file :)

  • I do not understand what you are saying.

  • I bought a PC with WIN8 installed. No installation discs came with it. Followed prompts to upgrade to 8.1. Since then my metro apps don’t work, as well as PC Settings and other problems. Same happened to my husband and he Reset back to WIN8 (also no discs, but his is a Dell and mine is HP). I can’t even do a system restore on mine. Have been using the internet from the desktop, but I want full use of my new computer.I have tried every “fix” I have found on various “forums” including Microsoft Support, to no avail. Many times I am met with complications preventing me to complete the suggested steps. My frustration is growing to the point of considering taking a sledge hammer to the cussed PC. Can’t afford a replacement, though. I was glad to find your article on how to reset w/o discs. Not too surprised to run into another complication :The “sources” file was found in $WINDOWS.~ BT and there is no install.wim there or anywhere on my PC. There is a recovery image on E: drive. I also was unable to create recovery discs on several attempts over the last year. HELP ?!

  • Kapil Arya

    ^^ Refer this to create System Recovery drive:

    Then you have to Reset or Refresh manually using System Recovery drive. Else you’d at least need the setup file to proceed according to this article.

  • Hi, not sure if this thread is still active as it seems fairly old but I’ll give it a shot and see if someone can help me. I want to restore my old PC which I originaly bought with Windows 7. I upgraded to Windows 8 upon it’s release then later to Windows 8.1. I do not have any physical discs for the installation, so I tried to follow the tutorial but I at step 3 I got stuck, I found the setup folder under C:/Windows/ but it was almost completely empty it only had one file in it called state, which then contained a document saying: [State] ImageState=IMAGE_STATE_COMPLETE
    Does anyone know what this means or what I can do? please respond as fast as possible and thanks

  • Kapil Arya

    ^^ You need to go Sources folder under Windows setup, not in system root drive.

  • Would I need the product key?

  • Kapil Arya

    ^^ Most probably, yes.

    Kindly help me.
    What could be the problem?

  • Kapil Arya

    ^^ Please refer:

  • I have Aspire VN7-591G laptop for a week now, and when I got it, it has a lot of pre-installed software and games and such, at first I played with them a little bit, but before receiving this laptop I have been reading a lot of review on it saying how a clean install or reinstalling windows should be done to get rid of what they called “bloatware”, so I blindly decided to do so cause it sounded kinda bad.

    What I did was I click the “remove everything and reinstall windows”
    After doing so, my laptop restarted and start to show those 0xc000000f error.

    I tried the reset and refresh, but I get the locked drive message and missing partition. I tried creating media provided by microsoft along with steps I see here and there, but there was not even an option to install them.

    Is it suppose to pop out or do we need to locate them ourself when we plug in the USB. I need more instructions, I’m such a noob in this kind of stuff, and I am super lost. One last try is by asking, I wanna try to fix it myself, if it still doesn’t work, guess I’ll have to make a trip back to the store for a fix.

    ^^ For “The drive where Windows is installed is locked. Unlock the drive and try again”, refer this:

  • sir i cant find the install.wim in source folder when i tried to makme recovery drive in my usb

  • Kapil Arya

    ^^ If you’ve ISO file, extract it, you’ll get the folder.
